Ap'pucation mea october 31, 1924. serial No. 747,104.

To all whom t may concern:

Be it known that I, LOUIS MAssUcER, a citizen of the French Republic,residing at Le Vesinet, Department of the Seine-et- Oise, in France, have invented certain new .Y and useful Improvements in Hood Latches;

and I do hereby declare the following to bel a full, clear, and exact description of the invention, such as will enable others skilled 1o in the art lto which it appertains to. make and use the same.

The present invention relates to a latch or fastener for hoods of any type, or for covs ers in general; its object consists 'essentially in the provision of avery simple strong clasp or latch which is economical in construction and exceedingly eiiicient in operation. This clasp or latch lenables the hoods or covers to be rapidly and firmly locked upon their seatings, and as easily unlocked, as desired. This advantage is especially appreciable in the case of hoods formotor cars and like power driven vehicles, which hoods are` often subject to chattering by reason of insuf-v icient rigidity of the latching device. Furthermorev this improved apparatus is inherently adapted for use as a lifting handle thus avoiding the necessity for lapplying to hoods or covers a member separately adapted for this purpose.

In the accompanyingl drawings:

Fig. 1 -is a longitudinal section taken through the latch, while in its locked position.

Fig. 2 is a similar view of the latch in its unlocked position.

l Fig. 3 is a section taken on the line 3-3 of Fig. 1.

Now referring specifically to the drawings; 1 indicates a movable portion of an automobile hood, adapted to be positioned against a stirrup 2, in which is mounted a rod 3, adapted to receive the hooked end 4 of the latching member, as will hereinafter be described. j

A tubular casing 5 extendsl obliquely through the hood section 1, and is rigidly secured thereto in lany desirable manner. A tubular member 13 is mounted within 50 the casing 5, and adapted for longitudinal reciprocation therein. Oppositesides of the Fmember 13 are slotted at 14, andthe sides of the casing 5 are similarly provided with registering slots, the construction being. clearly shownin Fig. 3, and' a stop pm 15,'

carrying a yblock 16, is mounted for reciprocation in said slots. 'Ihe block 16 is of disklike formation, and conforms to theinner walls of the member 13, and serves as an abutment for the lower end of a coiled spring 21, to .be hereinafter referred to.-

The upper end of the member 13` is provided with a slot 17, which spirally extends around said member, and which is adapted to receive a pin 18, fixed to project from a stem 19 projecting through the outer end of the casing 5. A hand-wheel 8 is rigidly secured to the end of the stem 19, and a collar 20 is secured to the upper portion of the stem 19, and engages an inwardly eX- tending flange 20, formed on the upper face of the casing 5, and limits outward movement of the stem 19.

'Ihe coiled spring 21 is mounted between the block 16 and the lower end of the stem 19, and is designed to retain the stem 19 in its uppermost position at all times, and to prevent any chattering of the latch.y 'y

In operation when it is desired to release the -hook 4 from the rod 3, the Wheel 8 is turned in an anticlockwise direction, there by causing the pin 18 to ride in the slot 17 and forcibly causing the member 13, under the camming action of the pin and slot construction, .to move downwardly, to the position shown inFig. 2, when the section 1 of the hood may be lifted. A reverse ro'- tation of the wheel 8 lwill manifestly operate to lift the member 13 to a position such that the hook 4 will engage therrod 3, as will be understood.

Modifications of the structure herein disclosed may be suggested to those skilled in the art, but my invention covers all embodiments falling fairly within the scope of the appended claims.

1. A latch for automobile hoods and the hke comprising a tubular casing extending through a movable portion of the hood, a

. hook member movable longitudinally of the casing, a fixed element beneath vthe said hood portion and adapted for operative connection with said hook member, a stem rotatably carried b the casing, and pin and slot connections. tween the stem and the hook member, whereby rotation of the `stem may cause the member to move longitudinally of the casing.

2. A latch for automobile hoods and the llol like comprising. a tubular casing extending through a movable portion of the hood, a

l hook member movable longitudinally of the y casing, a ixed element below said hood and adapted for operative connection with said hook member, a rotatable stem mounted within'the casing, a spiral slot in said hook member, and a pin projecting from said stem and extending into said slot, whereby rotation of the stemwill move the hook member longitudinally of said casing.

3. A latch for automobile hoods and the like comprising atubular casing extending through a movable portion of the hood, 'a hook member movable longitudinally of the casing, a fixed element below said hood and adapted for operative connection with said hook member, a rotatable 'stem mounted within the casing, a spiral slot in said hook member, a pin projecting from said stem and extending into said slot, whereby rotation of the stem will move the hook member j longitudinally of said casing, and means for limiting the movement of said hook member. *f

4. A latch for automobile hoods and the like comprising a tubular casing extending through a movable portion of the hood, a hook member movable longitudinally of the casing, a fixed element below said hood and adapted for operative connection with said hook member, a rotatable stem mounted within vthe casing, a spiral slot 1n said hook membeig a pin projecting from said stem and extending into said Slot, whereby rotation of the stem will move the hook member longitudinally of said casing, and means for limiting the movement of said hookmem- -ber, said means comprising registering clsed slots in the casing and` hook member, and a pin slidably movable .withm sald slots. y

5. A latch for automobile hoods and the like comprising a tubular casing extending through a movable portion of the hood,

a hook member movable longitudinally of the casing, a fixed element below said hood and adapted' for operative connection with said hook member, a rotatable stemvmountedwithin the casing, a spiral slot in said hook member, a pin projecting from said stem and extending into said slot, whereby rotation of the stem will move the hook member longitudinally of said casing, arrdmeans for 6. A latch for automobile hoods and the a like comprising a tubular casing extending through -a movable portion of the hood, a hook member movable longitudinally of the casing, a fixed element below said hood and adapted for operative connection with said hook member, a rotatable stem mounted within the casing, a spiral slot 'in said hook member, a pin projecting from said stem and extending `into said slot, whereby rotation of the stem will move the hook member longitudinally of said casing, and means for preventing rotation of said hook member with respect to said casing, said means comprisin g registering closed slots extending longitudinally of said casing and said member, and a pin riding in said slots.

7. A latch for automobile hoods and the like'comprising a tubular casing extending through a movable portion of the hood, a hook member movable longitudinally of the casing, a ixed element beneath the said hood portion and adapted for operativeconnection with said hook member, a stem rotatably carried bly the casing, cam connections vbetween the stem and the hook member, whereby rotation of the stem will cause the member to move longitudinally of the casing, and means for limiting the downward movement of said stem.

8. A latch for automobile hoods and thc like comprising a tubular casing extending through a movable portion of the hood, a hook member movable longitudinally of the casing, a fixed element beneath the said hood portion and adapted for operative connection with .said hook member, a stem rotatably carried by the casing, cam connections between the stem and the hook member, whereby rotation of the stem may cause the member to move longitudinally of thelcasing, and means for limitingthe downwardv In testimony whereof I hereunto affix my i signature.
